It looks like Pine Trail isn't done their Intel Atom line-up yet. Later this year, Intel will be launching the Atom N455 and the N475 which will be the same as the new Atom N450 and N470 CPUs except they'll have support for DDR3 RAM. The clock speeds will be the same, but you'll receive a significant boost in speed since DDR3 RAM is faster than DDR2. These two CPUs will launch in Q3 of this year.
